GHI Productivity Data Featured in Congressional Testimony on 2018 Farm Bill

Posted by on March 16th, 2017 | 0 Comments »

Global Harvest Initiative (GHI) and its 2016 Global Agricultural Productivity Report® (GAP Report®) were featured by Dr. Jay Akridge, Dean of Agriculture at Purdue University, during his testimony before the U.S. House of Representatives Committee on Agriculture Subcommittee on Biotechnology, Horticulture and Research on March 16, 2017.

Dr. Akridge testified to the critical importance of funding for agricultural research, education and extension programs in the 2018 Farm Bill. Drawing on language from the 2016 GAP Report®, Dr. Akridge said agricultural R&D is an “essential public good” and the principal driver of agricultural productivity.

His written testimony included two charts from the 2016 GAP Report® showing the growth of Total Factor Productivity (TFP) in low-income and high-income countries. He emphasized that TFP must grow globally by 1.75 percent per year to sustainably feed a growing world, a metric tracked by GHI’s Global Agricultural Productivity Index™. (See the 2016 GAP Index™ below.) “Investment in agricultural research will be a fundamental determinant of whether or not this level of productivity growth is achieved,” he said.

Feeding a Growing World

According to the U.S. Census Bureau, the United States gains one new person every 16 seconds; the world gains a new person about every half a second4. At present rates, the global population will reach 9.6 billion by 2050, and experts believe that agricultural productivity must increase 25 - 100% from current levels to feed a global population of that magnitude5. The challenge here is more than producing calories, it is about providing proper nutrition for a growing population6. And, this challenge is more than a food security issue, it is a national security issue as food insecurity and political instability are tightly linked7. This task is also made more challenging by a variety of factors: limited land and water resources, increasingly variable weather, natural a variety of factors: (pests and weeds resistant to insecticides and herbicides, for example), societal attitudes toward science and technology, and barriers to adoption of improved farming practices globally.8,9

The Global Harvest Initiative (GHI) has worked to quantify the challenge of feeding a growing world and measuring the current status of our ability to meet that challenge. The charts above and below are from the GHI’s 2016 Global Agricultural Productivity Report and demonstrate the profound difference that Total Factor Productivity (TFP) has made in the developed world over the past 50 years. TFP is the ratio of agricultural outputs (gross crop and livestock output) to inputs (land, labor, fertilizer, machinery and livestock). When TFP rises, more output can be produced from a fixed amount of inputs. TFP growth can result from increased effectiveness of inputs, more precise use of inputs, or adoption of improved production practices.10

GHI reports that TFP must grow by 1.75% annually for the world to double agricultural output through productivity gains by 2050. lnvestment in agricultural research will be a fundamental determinant of whether or not this level of productivity growth is achieved.

According to the GHl’s 2016 Global Agricultural Productivity Report, “Agriculture research and development (R&D) and extension programs are essential public goods and the principal drivers of TFP. Along with private sector and collaborative research, public R&D in agriculture plays an essential role in fostering agricultural innovation systems.” The report goes on to state that publicly funded agricultural research generates technologies and innovation that enhance farmer productivity and competitiveness, reduce waste in the food value chain, and ultimately benefit consumers through lower prices and improved access to safe and nutritious food.

Purdue University is a consultative partner of Global Harvest Initiative and provides content for GHI’s annual GAP Report. The 2016 GAP Report® features a story (page 58) on the Feed the Future Innovation Lab for Food Processing and Post-Harvest Handling based at Purdue and it’s work to create employment opportunities for Senegalese women in food processing, sales and marketing.
